This machine may be made of any suitable material, as Wood, iron, or other metal, or of wood and metal combined, and any power, either animal or steam or other motor, may be applied to the end of the long levers O U.

In the case of horses or mules, they will be hitched in the usual manner to the ends 0 c, and in walking around the circle the distance traveled is no greater than if attached to the short arms of lever B at b b.
